“…As for pure gases, a lot of models are derived from macroscopic thermodynamics development. The most useful predictive theories for multi-component adsorption equilibria are described in [1][2][3][4][5][6][7][8][9][10][11]. They are considered as efficient tools for engineers concerned with adsorption process design.…”

A unified approach based on statistical thermodynamics developments. Part II : Extension to gas mixture adsorption.. Molecular Simulation, Taylor & Francis, 2006, 32 (07) AbstractTheoretical description of single gas and gas mixture adsorption equilibria can be achieved in many different ways depending on the kind of approach (microscopic or macroscopic). In this paper, we present a statistical thermodynamics approach for the calculation of mixed gas adsorption equilibrium data on uniform surfaces. The non-ideality of both the mixed gas phase and the adsorbed phase is considered by using the Redlich-Kwong EOS associated to the classic Lorentz-Berthelot mixing rules. This is an interesting way to extend the model presented in Part I and to predict multicomponent gas adsorption equilibria for highly nonideal systems from parameters deduced from pure gas data. We present mixture adsorption isotherms and selectivity curves calculated using our model.

Microwave-assisted pyrolysis of HDPE using an activated carbon bed

Plastics play an enormous role in modern manufacturing, but the extraction and refining of raw materials, followed by the synthesis of plastics themselves, represents an enormous energy investment into a product that is all too often simply "thrown away" into a landfill after a single use. Microwave-assisted pyrolysis is a recycling technique that allows the recovery of chemical value from plastic waste by breaking down polymers into useful smaller hydrocarbons using microwave heat in the absence of oxygen. This dissertation examines the use of a catalytic activated carbon bed in this procedure, using high density polyethylene (HDPE) as a model plastic. Initial tests with the batch input of HDPE produced a condensed pyrolysis oil comprising 35.5-45.3% aromatics, with the remainder primarily short-chain aliphatics. This oil was approximately three times lighter than that produced in the absence of catalyst, with a narrower range of molecular masses that matched those of the liquid transport fuels petrol and diesel (C 5-C 21). The non-condensable gases that resulted were short-chain aliphatics that could be used as feedstock for the creation of new chemicals (such as virgin HDPE), or fuels such as natural gas and LPG. The development of apparatus capable of adding sample in a continuous fashion enabled the processing of larger quantities of HDPE, and resulted in condensed products with a significantly higher aromatic content (>80% at 450°C), and which I owe a debt of thanks to many people for the support and kindness they have shown me throughout my time in Cambridge. I would like to thank my supervisor, Professor Howard Chase, for his generous provision of tutelage, expertise, and support throughout the production of this work. A further thank you to my colleagues and the department support staff for their extremely skilled time and advice. I would also like to acknowledge the generous financial support that I have received from the Cambridge Commonwealth Trust, The Higher Education Funding Council for
